Answer:
21.6 grams
Explanation:
First we <u>convert 10 g of N₂ into moles</u>, using its <em>molar mass</em>:
- 10 g ÷ 28 g/mol = 0.36 mol N₂
Then we <u>convert 0.36 moles of N₂ into moles of NO</u>, using the <em>stoichiometric coefficients of the balanced reaction</em>:
- 0.36 mol N₂ *
= 0.72 mol NO
Finally we <u>convert 0.72 NO moles into grams</u>, using its <em>molar mass</em>:
- 0.72 mol NO * 30 g/mol = 21.6 g

Answer:
36
Explanation:
products and reactants have to be equal
Answer:
1) d = 2.4 g/cm³
2) m = 25 g
3) v = 126.7 cm³
Explanation:
Given data:
Mass of material = 24 g
Volume of material = 10 cm³
Density of material = ?
Solution:
Formula:
d = m/v
by putting value,
d = 24 g / 10 cm³
d = 2.4 g/cm³
2) Given data:
Density of material = 5 g/cm³
Volume of material = 5 cm³
Mass of material = ?
Solution:
Formula:
d = m/v
5 g/cm³ = m / 5 cm³
m = 5 g/cm³×5 cm³
m = 25 g
3)Given data:
Density of material = 3 g/cm³
Mass of material = 380 g
Volume of material = ?
Solution:
Formula:
d = m/v
3 g/cm³ = 380 g / v
v = 380 g /3 g/cm³
v = 126.7 cm³
