I believe its n= m/M
n - number of moles
m - mass of substance
M - molar mass of substance
The change that would cause an increase in the no. of deaths in the little population of wee bug would be:
b). Decrease Greenleaf
c). Increase Furbil
<u>Wee bug Population</u>
- As per the question, the decrease in Greenleaf would result in reduced eatables for the wee bugs.
- While the increase in Furbil would cause a threat to the population of the wee bug.
- As a result, due to decreased food and increased energy storage by Furbils would increase the death of wee bug population.
Thus, <u>options b and c </u>are the correct answers.

Explanation:
Calculate the mass of NaOH required to prepare a 0.343 M solution dissolved in 2500 mL of water. 0.343 M = x mol / 2.5 L = 0.86 mol 0.86.
Answer:
AuCl
Explanation:
Given parameters:
Mass of Gold = 2.6444g
Mass of Chlorine = 0.476g
Unknown:
Empirical formula = ?
Solution:
Empirical formula is the simplest formula of a compound. Here is the way of determining this formula.
Elements Au Cl
Mass 2.6444 0.476
Molar mass 197 35.5
Number of moles 2.6444/197 0.476/35.5
0.013 0.013
Divide by the
smallest 0.013/0.013 0.013/0.013
1 1
The empirical formula of the compound is AuCl
