7h2o2 + n2h4 → 2hno3 + 8h2o ; (h=1; n=14; o=16) 1. berapa mol hno3 yang terbentuk dari 0,025 mol n2h4? 2. berapa mol h2o2 yang dibutuhkan jika 1,35 mol h2o yang terbentuk? 3. berapa gram h2o2 yang dibutuhkan untuk menghasilkan 45, 8 g hno3?

(H = 1; N = 14; O = 16) 1. How many moles of are formed from 0.025 moles of ? 2. How many moles of are needed if 1.35 moles of are formed? 3. How many grams of are needed to produce 45, 8 g of ?

1. 0.05 moles of

2. 1.18 moles of

3. 86.5g of

Explanation:

First write the balanced chemical equation given by the problem:

1. Calculate how many moles of are formed from 0.025 moles of using the reaction stoichiometry:

2. Calculate how many moles of are needed if 1.35 moles of are formed using the reaction stoichiometry:

3. Calculate how many grams of are needed to produce 45,8 g of :

- Calculate the molar mass of the :

Molar mass H: 1

Molar mass O: 16

Molar mass =(2*1)+(2* 16)=34

- Calculate the molar mass of the :

Molar mass H: 1

Molar mass N: 14

Molar mass O: 16

Molar mass =(1*1)+(1*14)+(3*16)=63

if you're asking what comes out, it's steam.
