The density of the rubber ball is calculated by the mass of the rubber ball divided by the volume of the rubber ball.
21mL-15mL=6mL which is the volume of the rubber ball
D=10g/6mL
D=1.666g/mL density of the rubber ball
Answer:
171.34 g/mol
Explanation:
Ba molar mass = 137.328 g/mol
O molar mass = 15.999 g/mol * 2 = 31.9980 g/mol
H molar mass = 1.008 g/mol * 2 = 2.0160 g/mol
137.328 + 31.9980 + 2.0160 = 171.3420 = 171.34 g/mol
Ionic bonds hold NaCl together
C: 4 H on the left and right, 4 O on both sides making it balanced
Answer:
1. liquid, gas, and solid
2. Liquid, solid, and gas particles are different by volume, and shapes they take in containers. Solid is tightly packed, liquid takes the shape of anything, and gas has neither volume or shape
