1 answer:
Answer:
b. contains more matter.
A golf ball has more mass than a tennis ball because<u> it contains more matter</u> .
Explanation:
Volume = Total space enclosed enclosed by a substance or quantity of 3-D space occupied by solid, liquid or gas.It is measures in or L.
<u>Mass = Total matter (content)</u><u> present in a given substance</u><u> . It is measured in Kg</u>.
Density = It is defined as mass per unit volume of a substance .
The density of golf ball is more because it has more mass or more matter (content)than that of tennis ball.

Answer:
Explanation:
From similar question, equation (b) is
Molecular Equation:
- Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)
Net Ionic Equation:
- Cu(s) + 2Ag⁺(aq) → Cu²⁺(aq) + 2Ag(s)
<u>1. Mole ratio:</u>
<u>2. Convert 1.147 g of Cu(s) to moles:</u>
- Atomic mass of Cu: 63.546g/mol
- Number of moles = mass in grams / atomic mass
- Number of moles = 1.147 g / 63.546 g/mol = 0.01805 mol Cu(s)
<u />
<u>3. Calculate the moles of Ag(s):</u>
<u />
<u>4. Convert 0.03610 mol Ag(s) to grams:</u>
- Atomic mass of Ag(s) = 107.868g/mol
- Mass = 0.03610mol × 107.868g/mol = 3.894g
