Determine the correct set-up below to determine what mass, in grams, of N2 is needed to completely react with 105 g F2 ?
neonofarm [45]

Answer:

C: 1 mol F2/38 g F2

Explanation:

The reaction equation is;

N2 + 3F2 = 2NF3

Now, to know how many grams, of N2 is needed to completely react with 105 g F2 and since the molar mass of N2 is 28.02 g/mol, Molar mass of F2 is 38 g/mol, number of moles attached to N2 and F2 in the reaction are 1 and 3 moles respectively, then we will have;

105 g F2 × 1 mol F2/38 g F2 × 1 mol N2/3 mol F2 × 28.02 g N2/1 mol N2

Option C is Thus correct

How many grams of water are needed to react with 485 g of calcium carbide
grigory [225]
The procedure for this is the next one:
moles CaC2 = 485 g/64.1 g/mol=7.57 
<span>moles H2O = 2 x 7.57 =15.1 </span>
<span>mass H2O = 15.1 mol x 18.02 g/mol=272.8 g

A 100-gram sample of sodium chloride (NaCl) consists of 60.66 g of chlorine and 39.34 g of sodium. What mass of sodium would mak
bonufazy [111]
The answer is 59.01 g

If a 100-gram sample of NaCl consists of 39.34 g of sodium, a 150-gram sample of NaCl will consist x g of sodium:

100 g : 39.34 g = 150 g : x
x = 39.34 g * 150 g : 100 g
x = 59.01 g
