Explanation:
0.0733L of 3.00 M CH3COOH solution is needed to provide 0.220 mol of CH3COOH.
<u>Explanation</u>:
Molarity, M = moles of the molecule / Liter of solution
Therefore, we can work backwards to find the number of litres of solution, if we are given the number of moles
The values are a given as,
The molarity of the solution =3.00M
The final moles = 0.220 moles.
0.220 mol CH3COOH ( 1L / 3.00 mol CH3COOH) = 0.220/3.00
=0.0733L of solution
Explanation:
step 1. an inequality has either a <, <=, >=, or a >.
step 2. 1 < 4 is an inequality.
step 3. the answer is A.
(a) The mass of hydrogen sulfide produced in the reaction is 9.44 g.
(b) Water is the limiting reagent in the given reaction.
<h3>
Mass of hydrogen sulfide produced</h3>
Al2S3 + 6H2O ---> 2Al(OH)3 + 3H2S
mass of water in the reaction = 6(18 g/mol) = 108 g/mol
mass of hydrogen sulfide in the reaction: = 3(34) = 102 g/mol
108 g/mol of H2O ------- > 102 g/mol of H2S
10 of H2O -----------> ?
= 9.44 g
Aluminum sulfide will be completely consumed by the reaction while some fraction of water will remain. Thus, water is the limiting reagent in the given reaction.

Answer:
Three.
Explanation:
When counting the number of significant figures in a decimal number, you start counting from the right of the decimal point.
0
.00203
Counting from left to right from the decimal point , there are 5 digits.
However, the zeroes before any natural number is not counted as a significant figure.
0.00
203
Thus, there are
3
significant figures ie. 203.
Note: any other numbers added to the right of
0.00203
is also counted as a significant number.
eg.
0.002031
has 4 significant figures.
eg.
0.002030
has 4 significant figures.
