Answer:
Explanation:
Not Many
1 mol of CO has a mass of
C = 12
O = 16
1 mol = 28 grams.
1 mol of molecules = 6.02 * 10^23
x mol of molecules = 3.14 * 10^15 Cross multiply
6.02*10^23 x = 1 * 3.14 * 10^15 Divide by 6.02*10^23
x = 3.14*10^15 / 6.02*10^23
x = 0.000000005 mols
x = 5*10^-9
1 mol of CO has a mass of 28
5*10^-9 mol of CO has a mass of x Cross Multiply
x = 5 * 10^-9 * 28
x = 1.46 * 10^-7 grams
Answer: there are 1.46 * 10-7 grams of CO if only 3.14 * 10^15 molecules are in the sample
A physical property does not change the substance.
Solubility would be the answer since all of the rest are changing the substance. They all deal with bonds except solubility.
Answer: D. Solubility
Answer:
Do you need the definition or the equation to find it?

New analysis through 2014 shows that temperature is once again rising at about the same pace as it did over the second half of the 20 th century. PRESS RELEASE. Using the data that were available at the time (through 2012), the last climate report from the Intergovernmental Panel on Climate Change concluded that there had been no statistically significant increase in global surface temperature
