Determine the molarity for the fixer Sodium carbonate decahydrate (I dissolved 127.62 grams of sodium carbonate for every 4 lite
grin007 [14]

Answer:

0.112 M.

Explanation:

  • Molarity is the no. of moles of solute in a 1.0 L of the solution.

M = n/V.

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

mass = 127.62 g.

molar mass = 286.138 g/mol.

V of the solution = 4.0 L = 4000.0 mL.

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

If the distance between two objects is increased, the gravitational force will _____.
Mila [183]

Answer:

Decrease by the distance squared

Explanation:

<u><em>Gravitation formula:</em></u>

F=\frac{GMm}{r^{2}}

where

'F' is the force of attraction between the two bodies (Gravitational force),

'G' is the universal gravitational constant,

'M' is the mass of the first object,

'm' is the mass of the second object and

'r'  is the distance between the centers of each object.

Hence, with the increase by distance between two objects , the gravitation decreases by the distance squared
