Answer:
38,640g
Explanation:
Since the density is in g/mL, we have to convert 2.000 liters to mil-liters to be able to successfully use the formula of M=V*D. Convert liters to mil-liters and you should have 2000mL in which you can plug into the equation of M= 2000mL*19.32g/mL, mL cancels, and you're left with 38,640g (here the significant figures are already in check).
Answer:
B. Precipitation
Explanation:
Precipitation is the scientific term for rain
Answer: 1/2L
Explanation:
Volume and pressure are changed, so use Boyle's law.
P1V1=P2V2
Convert 303.9kpa to atm by mutiplying by (1/101.3)=3atm
Plug in:
1.5(1)=3(V2)
V2=1/2 L
This makes sense since volume and pressure are inversely proportional. The pressure is increased, so the volume must decrease.
Water. The energy from the fission reaction is used to heat water. The water vaporizes which causes pressure rise. The pressure is used to drive a turbine which runs a generator.
I hope this helps.
306.0g/22.5mL= 13.6 mL/g
D=m/v
The mass is 306.0
The volume is 13.6
