Answer: 2800 g
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number of particles.
Given mass = 5 kg = 5000 g
1 mole of produces = 1 mole of
50 moles of produces =
of
Mass of
2800 g of is produced from 5.0 kg of limestone.
Answer:
0.0451 mol FeCl₂
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
Explanation:
<u>Step 1: Define</u>
5.72 g FeCl₂
<u>Step 2: Identify Conversions</u>
Molar Mass of Fe - 55.85 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of FeCl₂ - 55.85 + 2(35.45) = 126.75 g/mol
<u>Step 3: Convert</u>
<u /> = 0.045128 mol FeCl₂
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
0.045128 mol FeCl₂ ≈ 0.0451 mol FeCl₂
Answer:
= 0.613dm^3
Explanation:
Data:
Molarity, M = 1.50M
no. of moles = 0.920 moles
volume=?
Solution:
as, molarity=
so, volume =
putting values:
=
volume = 0.613dm^3
