Answer: 100 %
%Abundance = part / total *100
%Abundance_1 = parts_1 / total * 100
%Abundance_2 = parts_2 / total * 100
%Abundance_3 = parts_3 / total * 100
%Abundace_1 + %Abundace_2+%Abundace_3 = parts_1/total *100 + parts_2/total*100 + parts_3/total*100
Factor the right side:
%Abundace_1 + %Abundace_2+%Abundace_3 = [parts_1+parts_2+part2_3]/total *100
Given the sum of the parts = total
%Abundace_1 + %Abundace_2+%Abundace_3 = [total]/total *100 = 100
So, the sum of the individual % of abundaces is 100 %.
Answer:
either deposition or physical weathering
Answer:
2.7 gm/cm cubed
Explanation:
To get the answer, you should divide the mass by the volume or 54 divided by 20 = 2.7
Answer:
Hence the evaporation rate in pints per minute is 0.001583.
Explanation:
Now,
1.5 gallons of paint are used.
It has 5% solid, so total 95% of 1.5 gallon can evaporate(only the solvent part will evaporate).
95% of 1.5 gallon=(95/100)*1.5 = 1.425 gallons.
1gallon = 8 pints.
So 1.425 gallons=8*1.425 pints
=11.4 pints.
Evaporation requires 2 hours. That is 3600*2 seconds = 7200 seconds.
So evaporation rate= 11.4 pints/7200 seconds.
=0.001583 pints per second
