Answer:

1.59 g

Step-by-step explanation:

To calculate the mass of Na2CO3 in 150 cm³ of a solution of concentration 0.1 mol/dm³, we need to use the following formula:

mass = concentration x volume x molar mass

Where:

concentration is the concentration of the solution in mol/dm³

volume is the volume of the solution in dm³

molar mass is the molar mass of the substance in g/mol

For Na2CO3, the molar mass is 106 g/mol.

First, we need to convert the volume from cm³ to dm³:

150 cm³ = 150/1000 dm³ = 0.15 dm³

Now we can substitute the given values into the formula:

mass = 0.1 mol/dm³ x 0.15 dm³ x 106 g/mol

mass = 1.59 g
