To teach you how to do this problem:
1. Look at the Periodic Table. O =16 grams/mole, H =1.01 grams/mole
2. Calculate the Molecular Weight of Water. 1*O + 2*H: 16+2.02=18.02g/mole
3. Divide the mass of what you have by the Molecular Weight: 35.1g H2O/(18.02 g H2O/mole H2O)
4. The units g H2O cancel leaving you with mole H2O.
5. 35.1 grams H2O= 1.95 moles H2O

∙ 15y agoFor this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the Atomic Mass. Multiply by one mole for units to cancel. H2O=18.0 grams
85.3 grams H2O / (18.0 grams) = 4.74 moles H2O

How many grams of O2 are in a 351 ml container that has a pressure of 12 atm at 25 Celsius?
You will be using the equation for the ideal gas law: PV=nRT, where P=pressure in atm, V=volume in liters, n=moles, R=ideal gas constant (0.0821) and T=temperature in kelvins, and along the way, you must convert mL to L and Celsius to kelvins. So, plug it all in: 12atm(0.351L) = n(0.0821)(298k). The answer is 0.17mol O2, which is about 2.7g O2.
What if your truck is a 1984 ford f 250 with a 351 it was assembled in the lorraine Ohio plant how do you know which 351 is in it?

How much ice would have to melt to lower the temperature of 352 ml of water?
Since you want your answer in grams of ice we need to convert 351 ml of water to grams. This is very easy for water since 1 ml of water weighs one gram. So we have 351 grams of water. We need to figure out how much energy we need to remove from the water. If you remove one calorie from one gram of water you will lower the temperature one degree C. So water has a specific heat (c) of 1 cal/g/C You have 351 grams and you want to drop the temp 20 degrees. You must remove q = mass x specific heat x temp change q = 351 grams x 1 cal/g/C x 20 degrees= 7020 calories now we need to figure out how much ice this will take. Melting one gram of ice requires 79.7 calories dividing we get ice required = 7020 calories/79.7 calories/grams = 88.1 grams of ice
