Answer:
The answer to your question is 27.3 %
Explanation:
Percent by mass = ?
Process
1.- Calculate the atomic mass of carbon using the periodic table
Atomic mass = 12g
2.- Calculate the molecular mass of CO₂.
Carbon = 12
Oxygen = 16 x 2 = 32
Total = 12 + 32 = 44g
3.- Calculate the percent by mass of carbon using proportions
44g -------------------- 100%
12 g ------------------- x
x = (12 x 100) / 44
x = 1200 / 44
x = 27.3 %
<span>27% thats it ^ u ^ yeah</span>
9 electrons :) I can't give a sbs explanation but here we go
When we convert the given mass in grams and volume in liters to m/v percent, we recall that m/v percent is expressed as grams/100 milliliters. In this case the expression becomes (50 grams/ 2500 L)*(0.1L/100ml), that is equal to 0.002 grams/ 100 mL. Hence the the concentration is equal to 0.2 m/v percent.
