Chemistry
1 answer:
AveGali [126]1 year ago
4 0

Answer:

11.29 kJ (to 4 sf)

Explanation:

Here, ammonia is the limiting reactant.

For the reaction to occur once, 4 moles of ammonia must be consumed.

Thus means that the reaction can occur 0.1579/4=0.039475 times.

Therefore, (286)(0.039475) = 11.29 kJ (to 4 sf)

Calculate the molarity of 6.631 g NANO3 in 100.0 mL of solution<br><br><br>add stepss
riadik2000 [5.3K]

Answer:

0.7802 M

Explanation:

<u>Data:</u>

  • V (volume) = 100.0 mL → V = 0.1000 L
  • m (mass) = 6.631 g → n = 0.07802 mol

<u>Wanted: </u>

  • M (Molarity)

<u>Equation: </u>

M = \frac{mol}{L}

<u>Solution:</u>

1. Convert mL to L:

  • V = 100.0 mL x \frac{1 L}{1000 mL} = 0.1000 L

2. Convert g to mol:

  • n = \frac{6.631 g}{84.9947 g/mol} = 0.07802 mol

3. Molarity Equation:

  • M = \frac{0.07802 mol}{0.1000 L} = 0.7802 M
