Power is the rate at which energy is?

Mrrafil [7]

In physics, power is the rate of doing work. It is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. In the SI system, the unit of power is the joule per second (J/s), known as the watt in honour of James Watt, the eighteenth-century developer of the steam engine.

6.75 L of carbon dioxide gas are stored at a pressure of 175 atm. If the temperature and number of gas particles do not change,

I am Lyosha [343]

Answer:

4.24 L

Explanation:

6.75 L - 175 atm

x. - 110 atm

175atm x=742.5L /atm

175atm 175atm

therefore x=4.24 L

How many grams Glycylglycine (molecular mass 132.119 grams/mole) are required to make 1 liter at 0.5 Molar concentration. If you

SOVA2 [1]

Explanation:

The given data is as follows.

Concentration of solution = 0.5 M

Volume of solution = 1 L

Molar mass of Glycylglycine = 132.119 g/mol

As molarity is the number of moles present in liter of solvent.

Mathematically, Molarity = $\frac{\text{No. of moles}}{\text{Volume}}$

Hence, calculate the number of moles as follows.

No. of moles = Molarity × Volume

= $0.5 M \times 1 L$

= 0.5 mol

Therefore, mass of glycylglycine = mol × molar mass

= $0.5 mol \times 132.119 g/mol$

= 66.06 g

Thus, we can conclude that 66.06 g glycylglycine is required.
