The answer to your question is 0.033 M

Explanation:

Data

moles of sucrose = 0.01

Molarity = ?

Volume = 300 ml

Formula

$Molarity = \frac{moles}{volume}$

Process

1.- Convert volume to liters using proportions

1000 ml --------------------- 1 liter

300 ml ------------------- x

x = (300 x 1) / 1000

x = 300 / 1000

x = 0.3 liters

2.- Substitute values in the formula

$Molarity = \frac{0.01}{0.3}$

3.- Simplification and result

Molarity = 0.033

1.consider the following balanced equation and answer parts a through. show calculations for each part.

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
