The molar mass of 
is 86.02 g/mole
.
<h3><u>
Explanation:</u>
</h3>
The molar mass of a chemical compound is represented as the mass of a unit of that compound separated by the number of substances in that unit, measured in moles. The molar mass is a volume, not molecular, the property of a substance.
The molar mass is a percentage of various examples of the compound, which usually change in mass due to the appearance of isotopes.
From the below attached table, the Molar mass of is 86.0108 g/mol.
Answer:
Yes, chromosomes are in the nucleus of all cells that have a nucleus.
Explanation:
Answer:
Mass = 381.28 g
Explanation:
Given data:
Number of moles of HNO₃ = 16 mol
Mass of Cu needed to react with 16 mol of HNO₃ = ?
Solution:
Chemical equation:
3Cu + 8HNO₃ → 3Cu(NO₃)₂ + 4H₂O + 2NO
Now we will compare the moles of Cu with HNO₃ from balance chemical equation.
HNO₃ : Cu
8 : 3
16 : 3/8×16 = 6
Mass of Cu needed:
Mass = number of moles × molar mass
Mass = 6 mol × 63.546 g/mol
Mass = 381.28 g
