Answer:
317.7778 g
Explanation:
Given data:
Flour required for 18 cup cakes = 260 g
Flour required for 22 cup cakes = ?
Solution:
We will calculate the flour required for 1 cup cake.
260 g /18 = 14.4444 g
Fluor required for 22 cupcakes,
22× 14.4444 g = 317.7778 g
In short,
22 cupcake/18 cup cake×260 g = 317.7778 g
In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. It is the mass of 1 mole of the substance or 6.022×10²³ particles, expressed in grams.
16 protons and 18 electrons gives the atom a -2 charge because there are 2 more electrons than protons. If it were 16 protons and 16 electrons, the charge would be 0 or neutral.
Califactual. thsi is correct bcuz carbon takes 20 minutes to dissolve and ring making it a factual
Pressure of the ideal gas=505.7kPa
Given:
No of moles=0.907mole
Temperature of the gas=
Volume of the gas=4.25L
To find:
Pressure of the gas
<u>Step by Step Explanation:
</u>
Solution:
According to the ideal gas equation
and from this pressure is derived as
Where P=Pressure of the gas
V=Volume of the gas=4.25L
n=No of the moles=0.907mole
R=Gas constant=8.314
T=Temperature of the gas= =273+12=285K
Substitute these known values in the above equation we get
P=505.7kPa
Result:
Thus the pressure of the ideal gas is 505.7kPa
