Whats the mass of a 1.25L sample of liquid that has a density of 0.921g/mL?

1 answer:

8 0

Hey there!

Volume in mL :

1.25 * 1000 => 1250 mL

Density = 0.921 g/mL

Therefore:

Mass = density * volume

Mass = 0.921 * 1250

Mass = 1151.25 g

Which type of equilibrium exists in a sealed flask containing Br2(ℓ) and Br2(g) at 298 K and 1.0 atm?(1) static phase equilibriu

marishachu [46]

The correct answer is 3.

A dynamic phase equilibrium is when a reversible reaction no longer changes its ratio of reactants to products. However, substances continue to move between the chemicals at an equal rate, which means the net change is 0. This is known as a steady state.

If you have 2L of a solution with 6 moles of HCl in it, what is the molarity of it?

Vladimir [108]

Answer:

Molarity = 3 M

Explanation:

Given data:

Volume of solution = 2 L

Number of moles of HCl = 6 mol

Molarity = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

by putting values,

Molarity = 6 mol / 2 L

Molarity = 3 M (M = mol/L)

n a coffee cup calorimeter, 100.0 mL of 1.0M NaOH and 100.0 mL of 1.0M HCl are mixed. Both solutions were originally at 24.6 deg

RoseWind [281]

Answer:

Explanation:

mass of the solution = volume x density = 200 x 1 = 200 gm

heat absorbed = m x s x Δ t , s is specific heat , Δt is rise in temperature

= 200 x 4.18 x ( 31.3 - 24.6 )

= 5601 J .

This is the enthalpy change required.

The organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.

<h3>What are organs?</h3>

Organs are a collection of tissues that are closely related and which perform a related function.

The role and function of the organs of the digestive system are as follows:

Pancreas - produces pancreatic juice which contain digestive enzymes
Liver - produces bile for the emulsification of fat
Stomach - serves as a temporary store of food and produces digestive juices
Small intestine - functions in food digestion
Large Intestine - helps to remove undigested food from the body

Therefore, the organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.
