6.00 g of a certain Compound X , known to be made of carbon, hydrogen and perhaps oxygen, and to have a molecular molar mass of  46. g/mol , is burned completely in excess oxygen, and the mass of the products carefully measured:   product mass carbon dioxide 11.48g water 7.05g Use this information to find the molecular formula of X .

Part a) Mr. Scholl likes to grow tomatoes in his backyard garden. Last year he grew a 6.27 × 10 to the power of -10 moles of tomatoes. How many tomatoes did he grow? Part b)The Waterloo Region has about 617,000 people in it. If Mr. Scholl divides his tomatoes equally among everyone in Waterloo Region, how many tomatoes will you personally receive (assuming you live in the Waterloo Region.)

Consider the balanced reaction 7 A + 6 B → 4 C + 7 D. If 3.361 moles of D (MW = 35.3) are produced, how many grams of B (MW = 38.62) are consumed?

Ammonium perchlorate (NH4C104) is the solid rocket fuel that was used by the U.S. Space Shuttle and is used in the Space Launch System (SLS) of the Artemis rocket. It reacts with itself to produce nitrogen gas (N₂), chlorine gas (C1₂), oxygen gas (O₂), water (H₂O), and a great deal of energy. What mass of oxygen gas is produced by the reaction of 9.70 g of ammonium perchlorate? Round your answer to 3 significant digits. g x10 X

A 3.000 g sample of a gaseous compound was found to contain 2.560 g of carbon and 0.440 g of hydrogen. A) What is the simplest formula of the compound (Write C first and then H)? You won't be able to make the numbers a subscript. For instance, for MgCl2 enter MgCl2. B) The molar mass of the compound was found to be 42.08 g/mol. What is the molecular formula of the compound? You won't be able to make the numbers a subscript. For instance, for MgCl2 enter MgCl2.

A combustion analysis is performed on a compound that contains only C and H. The analysis produces 7.69 g of CO2 and 3.17 g of H20. In addition, it was determined that the molar mass of the compound is 56.107 g/mol. Determine the molecular formula of the compound. Given molar masses: CO2: 44.009 g/mol; H2O: 18.015 g/mol Enter integer values below. type your answer... H. type your answer...
