(YOU MUST SHOW YOUR WORK AS MODELED IN CLASS IN ORDER TO RECEIVE CREDIT!!!) Answer The Following Questions:

1. What is the mass in grams of 2.64 mol of sulfur dioxide, SO2?

2. Calculate the mass of 3.57 mol of magnesium nitrate, Mg(NO3)2.

3. How many moles are there in 79.0 g Li2SO4?

4. What is the mass in grams of hydrogen in 215 g of sugar, C12H22O11?

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong
