Answer:
1.602 L (or) 1602 mL
Explanation:
Molarity is the amount of solute dissolved per unit volume of solution. It is expressed as,
Molarity = Moles / Volume of Solution ----- (1)
Rearranging above equation for volume,
Volume of solution = Moles / Molarity -------(2)
Data Given;
Molarity = 0.00813 mol.L⁻¹
Mass = 1.55 g
First calculate Moles for given mass as,
Moles = Mass / M.mass
Moles = 1.55 g / 119.002 g.mol⁻¹
Moles = 0.0130 mol
Now, putting value of Moles and Molarity in eq. 2,
Volume of solution = 0.0130 mol / 0.00813 mol.L⁻¹
Volume of solution = 1.60 L
or,
Volume of solution = 1602 mL
What biochemical reaction??
Answer:
Maximum gravitational Force: 
Explanation:
The maximum gravitational force is achieved when the center of gravity are the closer they can be. For the spheres the center of gravity is at the center of it, so the closer this two centers of gravity can be is:
bowling ball radius + billiard ball radius = 0,128 m
The general equation for the magnitude of gravitational force is:
Solving for:
The result is:
Answer:
Baking soda
Explanation:
Due to its neutralizing properties, sodium bicarbonate can be used to counteract the acid corrosion of car batteries. To use baking soda, in this case, be sure to disconnect the battery terminals before cleaning. Make a paste of three parts baking soda to one part water and apply with a damp cloth to rub the corrosion of the battery terminal. After cleaning and reconnecting the terminals, clean them with petroleum jelly to prevent future corrosion.
Formula units in 450 g of 
is 1.93 × 10²⁴ formula units.
<u>Explanation:</u>
First we have to find the number of moles in the given mass by dividing the mass by its molar mass as,
Now, we have to multiply the number of moles of Na₂SO₄ by the Avogadro's number, 6.022 × 10²³ formula units/mol, so we will get the number of formula units present in the given mass of the compound.
3.2 mol × 6.022 × 10²³ = 1.93 × 10²⁴ formula units.
So, 1.93 × 10²⁴ formula units is present in 450g of Na₂SO₄.
