Answer:
About 0.4143M
I gave you extra numbers after the decimal point in case you have to round higher.
Step-by-step explanation:
Molarity is the Moles per liter ratio so we need to find how many moles of KBr are in 35 grams which is about 0.29 moles.
So no (0.29)/(0.7)=0.4143
The 0.7 is from 700ml is 0.7 Liters.
