Answer:
Percentage of copper = 88%
Explanation:
Given data:
Mass of copper = 51.2 g
Mass of tin = 6.84 g
Percentage of copper = ?
Solution:
Formula:
Percentage of copper = mass of copper / total mass × 100
Now we will determine the total mass:
Total mass = mass of copper + mass of tin
Total mass = 51.2 g + 6.84 g
Total mass = 58.04 g
Now we will calculate the percentage of copper.
Percentage of copper = 51.2 g / 58.04 g × 100
Percentage of copper = 0.88 × 100
Percentage of copper = 88%
24 gravity
26force
is the answer
This might get a little salt out but you will need to evaporate the water to completely get the salt out. Once you evaporate the water all that will be left is the salt
Answer is: mass of product is 649.35 g.
Balanced chemical reaction: Ca(s)+Cl₂<span>(g) → CaCl</span>₂<span>(s).
m(Ca) = 23.4 g.
n</span>(Ca) = m(Ca) ÷ M(Ca).
n(Ca) = 23.4 g ÷ 40 g/mol.
n(Ca) = 0.585 mol.
From chemical reaction: n(Ca) : n(CaCl₂) = 1 : 1.
n(CaCl₂) = 0.585 mol.
m(CaCl₂) = 0.585 mol · 111 g/mol.
m(CaCl₂) = 649.35 g.
