Answer:
Percent by mass is calculated by tihis formula, Mass of solute (g) ÷ mass of solution (g)] × 100.
Explanation:
For example: if you have a solution 45% m/m (mass percentege), you have 45 g of solute in 100 g of solution.
Answer:
More particles per unit volume
Explanation:
Concentration means the amount of solute in a solution. Now, the amount of solute also means the number of particles of solute present in a solution.
Hence, when we use the term "high concentration", we imply that the amount of solute present or the number of particles present in a solution is high.
Thus, at high concentration, there are more solute particles than solvent particles in a solution.
The answer is d. 2 hope this helps
The value of the coefficient x in the balanced equation can be calculated as :
<span>
x/y </span>= <span><span>26.4[mL]/</span><span>6.6[mL<span>]
x/y = 4</span></span></span>
divide 5 hours 20 mins by 4,000
and ur answer is
320 mins/4000km
so
0.08
hope this helps
sorry if its wrong
