Answer:
MgN3
Explanation:
In MgN3 the charge on the ionic species is greater than NaCl. So,ionic interactions in MgN3 will be stronger
Answer: 2.23 grams
Explanation:
Nitrogen dioxide is an oxide of nitrogen with a chemical formula of NO.
Given that:
mass in grams of NO = ?
Number of moles of NO = 67mol
Molar mass of nitrogen dioxide NO, use the atomic mass of nitrogen = 14g; Oxygen = 16g
NO = (14g + 16g) = 30g/mol
Now, apply the formula:
Number of moles = (Mass in grams / Molar mass)
67 moles = (Mass / 30g/mol)
Mass = (67moles/30g/mol)
Mass = 2.23 grams
Thus, there are 2.23 grams of Nitrogen dioxide present
