To soften cloths in the wash it is recommended to use 2.0 g of sodium borate per liter of water. If a filled washing machine holds 10 L of water and the correct amount of sodium borate per liter is added, what is the concentration in percent mass/volume of the solution?

% m/v of the solution = 0.2%m/v

or

% m/v = g solute / 100 ml solution

Concentration : 2 g sodium borate / L water

For 10 L⇒20 g Sodium borate

it is stable as it is in group 0 which have full outer shells of electrons

answer: mole of the gas

answer: mole of the gasexplanation:
