Determine the molarity for the fixer sodium carbonate decahydrate (i dissolved 127.62 grams of sodium carbonate for every 4 liters of water)

0.112 M.

Explanation:

M = n/V.

M = (mass/molar mass)solute x (1000/V of the solution).

mass = 127.62 g.

molar mass = 286.138 g/mol.

V of the solution = 4.0 L = 4000.0 mL.

∴ M = (mass/molar mass)solute x (1000/V of the solution) = (127.62 g / 286.138 g/mol) x (1000 / 4000.0 mL) = 0.1115 M ≅ 0.112 M.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
