I can help you! What is your question?
When writing an ionic compound formula, a "molecular" form is used. The formula is made with allowance for ion charges.
For example,
Ca²⁺ and NO₃⁻ ⇒ Ca(NO₃)₂
Al³⁺ and SO₄²⁻ ⇒ Al₂(SO₄)₃
M/V=D
65.14/35.4≈1.84
The density of the sulfuric acid would be about 1.84g/mL
