Recall that density is Mass/Volume. We are given the mL of liquid which is volume so all we need is mass now. We are given the mass of the granulated cylinder both with and without the liquid, so if we subtract them, we can get the mass of the liquid by itself. So, 136.08-105.56= 30.52g. This is the mass of the liquid. We now have all we need to find the density. So, let’s plug these into the density formula. 30.52g/45.4mL= 0.672 g/mL. This is our final answer since the problem requests the answer in g/mL, but be careful, because some problems in the future may ask for g/L requiring unit conversions. Also note that 30.52 was 4 sigfigs and 45.4 was 3 sigfigs, and so dividing them required an answer that was 3 sigfigs as well, hence why the answer is in the thousandths place
Answer: The total pressure will be 1,11,720 torr.
Explanation:
Partial pressure of nitrogen gas.
(1atm = 760 torr)
Partial pressure of oxygen gas,
Total pressure, in torrs, of the scuba gas mixture = 40280 + 71440 torr =111,720 torr
Hence , the total pressure in scuba gas mixture is 111,720 torr.
The various atomic masses of the same element are called<u> isotopes</u>. They have the same number of protons but different number of neutrons.
