You would have the same amount, the density will change, not the mass
<span>When heating lithium carbonate (Li2CO3), it will dissociate to Li2O and Co2. So the balanced chemical equation of this reaction is Li2CO3 = Li2O + CO2.
</span>
oxygen added to the copper is 3.300 grams.
<span>89.920 - 83.620 = 3.300 g oxygen </span>
<span>which is 0.2063 moles of oxygen. </span>
<span>3.300 g O x (1 mol O / 16.00 g O) = 0.20625 mol </span>
Answer:isotopes
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.
Explanation:
<h3>
Answer: 4.25 g/ml %</h3>
Explanation:
weight/volume percentage concentration = (mass in g ÷ volume) × 100
= (0.850 g ÷ 20 ml) × 100
= 4.25 g/ml %
∴ the weight/volume percentage concentration of the sucrose solution is 4.25 g/ml %.
