Answer:
3.46 x 10²⁴ molecules.
Explanation:
- <em>Knowing that every one mole of a substance contains Avogadro's no. of molecules (NA = 6.022 x 10²³).</em>
<em><u>Using cross multiplication:</u></em>
1.0 mole of HBr → 6.022 x 10²³ molecules.
5.75 mole of HBr → ??? molecules.
∴ The no. of molecules of HBr are in 5.75 mol = (6.022 x 10²³ molecules) ( 5.75 mole) / (1.0 mol) = 3.46 x 10²⁴ molecules.
(2.32g/cm³) x (1kg/1000g)x(1 000 000 cm³/1m³) = 2320 kg/m³
1 ml= 1 cm³
Because its where the warm water is, the warmer the water, the stronger the hurricane, and plus its tides that brings the warm water

Answer:
M = 63.02g/mol
Explanation:
Molar mass = the atomic masses of each atom combined
H = 1.01
N = 14.01
O = 16.00
M = 1.01(1) + 14.01(1) + 16.00(3)
M = 63.02
Therefore the molar mass of nitric acid is 63.02g/mol
