In 2014 (the last year for which I can find data), Utah County had a carbon monoxide (CO) average concentration of 1.90 ppm. (1 ppm stands for 1 part per million which means in one million volumes of air—choose whatever volume unit you like—there would be one volume of carbon monoxide.) An average human takes inhales 0.50 L per breath and takes 20 breaths per minute. Carbon monoxide in the atmosphere has a density of 1.2 grams per liter. 2. How many liters of carbon monoxide will a person breathe in Utah County in 8 hours?

A bottle of drinking water is labeled 24 fluid ounces (710 mL).” What is the mass in milligrams of 0.69 fluid ounces of the H2O?   Suppose that silver is selling for $308 / lb. How many grams of silver could you buy for one dollar?

Can you actually write this out? It makes it much more difficult to read when it gets written out this way.     Step 1 Here we are required to find the mass of sap that would be needed for making 1kg of syrup Step 2 Here mass of maple syrup =1 kg % of sucrose in the syrup= 66% We define w/w% as the mass of solute present in 100 gm of solution  So  w/w% =mass of solute ×100mass of solutionw/w of sucrose% =mass of sucrose ×100mass of maple syrup66= mass of sucrose ×1001kgmass of sucrose =66 ×1kg100=0.66kg so in 1kg of maple syrup 0.66 kg of sucrose is presentgiven in maple sap 4% sucrose present we need to find the mass of sap which contain 0.66 kg of sucrosew/w of sucrose% =mass of sucrose ×100mass of maple sap4=0.66kg ×100mass of maple sapmass of maple sap =0.66kg ×1004=16.5 kg

A student follows a lab protocol that asks them to make an ‘alcohol’ solution for an experiment. They make a 1.00 L solution by adding 575 g of an alcohol to water. Later they realize that there were three different alcohols sitting on the lab bench and they’re not sure which one they used. The alcohols are: methanol (CH3OH), ethanol (C2H5OH), and butanol (C4H9OH). They decide to boil the solution and they find that it boils at 106.40 °C. Using this information determine which alcohol the student used to make their solution. Density of water is 1.00 g/mL, Kb = 0.513 K/mc. Hint: you need to consider the molar masses of your alcohols.

The study of detecting small quantities of substances in samples would most likely be performed by a chemist in the branch of chemistry known as ___ . organic chemistry biochemistry inorganic chemistry analytical chemistry physical chemistry

What are three physical changes you encounter on a daily, weekly, or monthly basis? What are three chemical changes you encounter on a daily, weekly, or monthly basis? Imagine what life would be like without these types of changes occurring around us all the time. What aspects of life would be significantly harder? Would any aspects of life be easier? Why are these changes essential to our daily life?

Which of the following are mixtures? salt (NaCl) air (mostly N₂ and O₂) water (H₂O) salt water
