Answer:

The full amount (5.00 g) will be dissolved in 1 L of water at 25°C.

Explanation:

The molecular weight (MW) of Vanillin (C₈H₈O₃) is calculated from the chemical formula as follows:

MW(C₈H₈O₃) = (12 g/mol x 8) + (1 g/mol x 8) + (16 g/mol x 3) = 152 g/mol

If 0.070 mol of C₈H₈O₃ are soluble per liter of water at 25°C, the maximum mass that can be dissolved in 1 L is:

0.070 mol x 152 g/mol = 10.64 g

Since 5.00 g is lesser than the maximum amount that can be dissolved (10.64 g), the added amount will be completely dissolved in 1 L of water at 25°C.

3) What is the mass of a sample consisting of 1.00 X 1022 formula units of MgSO.?(​
Montano1993 [528]

number of moles = 1.00 X 10^22 ÷ 6.022 × 10^23

= 0.0166 moles

mass = number of moles × molar mass

= 0.0166 × 120.37 = 2.00 g
