Answer:
300g of water was used to make the solution
Explanation:
In the sugar solution, there are dissolved 45g of sugar in 100mL of water. The conversion factor is <em>45g Sugar = 100mL water</em>. That means when 135g of sugar are used the amount of water is:
135g sugar * (100mL water / 45g sugar) =
<h3>300g of water was used to make the solution</h3>
Answer:
A.He added bleach to the samples.
Explanation:
Bleach destroys the chemical composition of bacteria. Adding mold spores, freezing samples, and raising the temperature all result in physical changes, but not chemical changes, so specimens remain alive.
ANSWER - 48.83%
Mg - 24.31
S - 32.07
O - 16x4 - 64
ADD ALL TOGETHER = 120.38
H - 1.01x2 - 2.02
O - 16
TOTAL = 18.02x7 = 126.14
ADD 120.38 to 126.14 = 246.52
last part divide MgSO4 by total compound mass
120.38/246.52 then multiply by 100 = 48.831
