7 0

Answer:

60.7%

Explanation:

Molar mass of NaCl = 23 +35.5

= 58.5 g/mol

Molar mass of Cl = 35.5 g/mol

Percentage by mass of Cl =?

The percentage by mass of Cl in NaCl can be obtained as shown below'

Percentage by mass = mass of element / mass of the compound × 100

Percentage by mass of Cl

= 35.5 / 58.5 × 100

= 3550 / 58.5

= 60.7%

Therefore, the percentage by mass of Cl in NaCl is 60.7%

Calculate the percent activity of the radioactive isotope strontium-89 remaining after 5 half-lives.
maria [59]
The answer to this question would be: 3.125%

Half-life is the time needed for a radioactive molecule to decay half of its mass. In this case, the strontium-89 is already gone past 5 half lives. Then, the percentage of the mass left after 5 half-lives should be:
100%*(1/2^5)= 100%/32=3..125%

MrRissso [65]
<span>There is only one formula to use and we should assume ideal gas. This equation is: PV=nRT. For the following questions manipulate this equation to get the answer.
 1. n = PV/RT = (249*1000 Pa)(15.6 L)(1 m^3/1000 L)/(8.314 Pa-m^3/mol-K))(21+273) = 1.59 mol
 2. P = nRT/V = (1.59)(8.314)(51+273)/(15.6/1000)(1000) = 274.55 kPa
 3. Since the answer in #2 is more than 269 kPa, then the tires will likely burst. 4. Reduce pressure way below the limit 269 kPa.</span>
