Answer:
D: 1.6 x 10^6
Explanation:
(4.5 x103)(3.5 x102
Multiply
4.5 x 3.5 = 15.75
Now add 10^3 + 10^2 because we are finding the product of this.
10^3 + 10^2 = 10^5
Use sig figs
15.75 rounded to the whole number is 16.
A scientific notation always has to only have the tenths place only.
Change 16 to 1. 6
Then change 10^5 to 10^6
And your final answer would be 1.6 x 10^6.

Answer: a) 0.06 M
b) 3.13 grams.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Moles of 
The balanced reaction for dissociation will be:

Thus for 4 moles of
, there is 1 mole of 
Thus moles of 
Molarity of 
Thus the molarity of the
solution = 0.06 M
b) Mass of
= 
Thus mass of
Wenzhou use is 3.13 grams.
