Recently one month's production of sodium hydroxide in the US was 2.15 billion pounds. The density of sodium hydroxide is 2.130 g/cm³. What is the volume in cubic kilometers that were produced? Finish with the correct sig figs

Aqueous sulfuric acid (H,SO4) will react with solid sodium hydroxide (NaOH) to produce aqueous sodium sulfate (Na, SO,) and liquid water (H,O). Suppose 42. g of sulfuric acid is mixed with 18.9 g of sodium hydroxide. Calculate the minimum mass of sulfuric acid that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits. g x10

A 15.6-g sample of sodium carbonate is added to a solution of acetic acid weighing 19.7 g. The two substances react, releasing carbon dioxide gas to the atmosphere. After reaction, the contents of the reaction vessel weighs 28.9 g. What is the mass of carbon dioxide given off during the reaction Mass = %3D

Given the following data, calculate the percentage of salt in the original mixture.  Include the % unit and two decimal places in your answer. Mass of mixture = 5.426 g Mass of 400 mL beaker = 137.521 g Mass of 400 mL beaker and sand = 139.477 g Mass of 250 mL beaker = 105.691 g Mass of boiling chips = 0.463 g Mass of 250 mL beaker + boiling chips + salt = 108.328 g

and gaseous Gaseous methane (CH4) will react with gaseous oxygen (O₂) to produce gaseous carbon dioxide (CO₂) water (H₂O). Suppose 0.80 g of methane is mixed with 1.22 g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. Round your answer to 3 significant digits. g x10 X Ś

Suppose you have 150. mL of a substance with a density of 48.0 g/dm3 and want to determine the mass of the substance. The calculation can be broken down into three steps. First, convert the volume from milliliters to liters. Then, convert the volume from liters to cubic decimeters. Finally, determine the mass of the sample in grams. Show the unit analysis by placing the correct components into the unit‑factor slots. The question marks (?) represent the answer to the previous step.

Aqueous hydrochloric acid (HCI) will react with solid sodium hydroxide (NaOH) to produce aqueous sodium chloride (NaCl) and liquid water (H₂O). Suppose 0.729 g of hydrochloric acid is mixed with 0.44 g of sodium hydroxide. Calculate the maximum mass of sodium chloride that could be produced by the chemical reaction. Round your answer to 2 significant digits. g x10 X 3 ? IFM d

A 0.790 gram sample of copper is carried through the steps of an experiment. At the completion of the last step of the experiment, 0.314 grams of copper are recovered. What is the percent recovery of the copper metal? Give your answer in in decimal format.

Aqueous hydrochloric acid  HCl  will react with solid sodium hydroxide  NaOH  to produce aqueous sodium chloride  NaCl  and liquid water  H2O . Suppose 28. g of hydrochloric acid is mixed with 53.0 g of sodium hydroxide. Calculate the minimum mass of hydrochloric acid that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits.

Liquid octane CH3CH26CH3 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 2.3 g of octane is mixed with 2.00 g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits. g
