How many grams of H2SO4 do I need to use in order to produce 3.01 moles of water? consider the equation. _Ca(OH)2 + _H2SO4 = _CaSO4 + _H20

148 g H₂SO₄

General Formulas and Concepts:

Chemistry - Stoichiometry

Explanation:

Step 1: Define

RxN:   Ca(OH)₂ + H₂SO₄ → CaSO₄ + H₂O

Given:   3.01 moles H₂O

Step 2: Balance RxN

Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O

Step 3: Define conversions

Molar Mass of H - 1.01 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of H₂SO₄ - 2(1.01) + 32.07 + 4(16.00) = 98.09 g/mol

Step 4: Stoichiometry

= 147.625 g H₂SO₄

Step 5: Check

We are given 3 sig figs. Follow sig fig rules.

147.625 g H₂SO₄ ≈ 148 g H₂SO₄

they begin to vibrate harder causing the material that was solid to turn into a liquid i.e gallium or ice

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
