Answer:

<h2>D. mass of reactants → mass of products </h2>

Explanation:

The only difference between the options are the sign. The sign between the two is an arrow to represent the change.

(I know this because we're learning about it in class and it's an arrow not an equal, greater, or less than sign)

If you dissolve 8.50 g of ca(no3)2 in 755 ml of distilled water what is the concentration in molarity of the calcium nitrate sol
Zanzabum
Molarity is defined as the number of moles of solute in 1 L of solution 
the mass of Ca(NO₃)₂ present - 8.50 g
therefore number of moles of Ca(NO₃)₂ - 8.50 g / 164 g/mol = 0.0518 mol
the volume of solution prepared is 755 mL 
therefore if there are 0.0518 mol in 755 mL 
then in 1000 mL the number of moles - 0.0518 mol / 0.755 L 
molarity is therefore - 0.0686 M
