The sum of the coefficients in the balanced chemical equation for combustion of acetone C3H6O in air is 11
explanation
<h2>
write a balanced chemical equation for reaction</h2>
that is; C3H6O + 4O2 → 3CO2 +3H2O
coefficient is the number in front of the chemical formula
the sum of coefficient is therefore= 1 ( in front of C3H6O) + 4 ( in front of O2) + 3 ( in front of CO2) + 3 ( in front of H2O) = 11

Answer:
grams of solute = 31.5 g
Explanation:
Given data:
Grams of solute = ?
%m/v = 3%
Volume = 1050 mL
Solution:
grams of solute = 3 g of NH₄Cl / 100 mL × 1050 mL
grams of solute = 0.03 g × 1050
grams of solute = 31.5 g
