Al(s) + NiSO4(aq)<br> Balance
irinina [24]

Answer:

2Al(s) + 3NiSO4 --> Al2(SO4)3 + 3Ni

Explanation:

This reaction type is a single replacement. The format of a single replacement is:

A+BC --> B+AC

A= Al

B= Ni

C= SO

The coefficient 3 for Ni would become a subscript for  AC. After you plug those into the reaction you need to count how many of each are on the left side and try to get the same number on the right side. Both sides must be equal to have a balanced equation.

What is the mass of solute in a 500 mL solution of 0.200 M
Fofino [41]

16.4 grams is the mass of solute in a 500 mL solution of 0.200 M .

sodium phosphate

Explanation:

Given data about sodium phosphate

atomic mass of Na3PO4 = 164 grams/mole

volume of the solution = 500 ml or 0.5 litres

molarity of sodium phosphate solution = 0.200 M

The formula for molarity will be used here to know the mass dissolved in the given volume of the solution:

The formula is

molarity = \frac{number of moles of solute}{volume in litres}

    putting the values in the equation, we get

molarity x volume = number of moles

0.200 X 0.5= number of  moles

number of moles = 0.1 moles

Atomic mass x number of moles = mass

putting the values in the above equation

164 x 0.1 = 16.4 grams

16.4 grams of sodium phosphate is present in 0.5 L of the solution to make a 0.2 M solution.
