Answer:
0.12 & of NaCl
Explanation:
Determine the percentage of NaCl in the broth
First of all, we convert the mass from mg to g
340 mg . 1g/ 1000 mg = 0.340 g
Now we can calculate the %
(0.340 g / 286.7 g) . 100 = 0.12 %
Answer:
The percent by mass of sodium chloride in the broth is 0.118 %
Explanation:
Step 1: Data given
Mass of sodium chloride = 340 mg = 0.340 grams
Mass of broth = 286.7 grams
Step 2: Calculate the total mass
Total mass = mass of sodium chloride + mass of broth
Total mass = 0.340 grams + 286.7 grams
Total mass =287.04 grams
Step 3: Calculate percent by mass of sodium chloride
% mass NaCl = (mass NaCl / total mass) *100%
% mass NaCl = (0.340 grams / 287.04 grams) *100 %
% mass NaCl = 0.118 %
The percent by mass of sodium chloride in the broth is 0.118 %
