Answer: 13.5g
Explanation:
Moles = mass/molar mass
Molar mass of water= 18gmol-1
0.75=m/18
m= 17*0.75= 13.5g
Answer:
alpha decay
Hope this helps. :)
a solvent is what is doing the dissolving. so in this case the water would be your solvent because it is dissolving the salt. does that make sense?
Answer:you need to write the equation of the reactions in each question.
you need to calculate the mol for each substance which mass for which mass is given
then you do mol ratio.
I hope this shows you a hint and helps you not to depend completely on brainly.
plz put me as Brainliest
Explanation:
Answer:
69.036 g of Compound is required to obtain 48.45 g of Oxygen.
Explanation:
Let us assume that the total mass of the compound is 100 g. So it means that this compound weighing 100 is composed 70.18 % of Oxygen or among 100 g of this compound 70.18 g is constituted by oxygen only. Hence, we can make a relation as that,
70.18 g O is present in = 100 g of a Compound
So,
48.45 g of O will be present in = X g of a Compound
Solving for X,
X = 100 g × 48.45 g ÷ 70.18 g
X = 69.036 g of Compound
