If you have 4.01 g of H2, how many grams of NH3 can be produced?
stellarik [79]

Answer:

136.5886g of NH3

Explanation:

N2 + 3H2 = 2NH3

The mass of the N2 = 4.01

3H2 has a 2/1 ratio

This means the mass of 3H2 is twice as much as N2.

NH3= 2*N2 = 2*4.01 = 8.02 of NH3

Then, by multiplying the mass by MX (17.031)

8.02*17.031=136.5886g can be produced. Round it if needed.

How many molecules are in 3.10*10^-3 g of C6H12O6
joja [24]
Molas mass C6H12O6 = 180.15 g/mol

1 mole C6H12O6 -------------- 180.15 g
?? molesC6H12O6 ------------ 3.10x10⁻³ g

3.10x10⁻³ x 1 / 180.15 => 0.00001720 moles

1 mole ------------------------- 6.02x10²³ molecules
0.00001720 moles ---------- ??

0.00001720 x (6.02x10²³) / 1 => 1.035x10¹⁹ molecules
