Answer:
V HCNsln = 0.9176 L
Explanation:
V HCNsln = ?
∴ m HCN = 31 g
∴ <em>C</em> HCNsln = 1.25 mol/L
∴ molar mass HCN = 27.0253 g/mol
⇒ V HCNsln = (31 g)*(mol/27.0253 g)*(L/1.25 mol) = 0.9176 Lsln
Argon is a pure element which means that it cannot be broken down further than it already is. Methane, however, is a hydrocarbon, which means it is made out of both hydrogen and carbon and thus can be broken down to separate those elements.
Answer:
15 protons
Explanation:
The atomic number always equals the number of protons inside the nucleus, so if the atomic number is 15, that means 15 protons are present.
706.1652 g is the molar mass of 4.68 mol of sodium bromate.
Given:
Sodium bromate is used in a mixture which dissolves gold from its ores.
Moles of sodium bromate= 4.68 mol
Molar mass of sodium bromate = 150.89 g/mol number of moles × mol
= 150.89 × 4.68
= 706.1652 g
Therefore, 706.1652 g is the molar mass of 4.68 mol of sodium bromate.
