Answer
C6H807 = 192.124 g/mol
n = m/M
n = 0.119 mol
Explanation:
to calculate amount in moles you need to find the molar mass of citric acid then divide the mass of the acid with the molar mass
Answer:
Percentage yield=79.14%
Explanation:
Percentage yield=(Actual yield/theoretical yield)*100
Percentage yield=27.7g/35.0g*100
Percentage yield=79.14%
Answer:
Below
Explanation:
The mole, symbol mol, is the SI base unit of amount of substance. The quantity amount of substance is a measure of how many elementary entities of a given substance are in an object or sample
Explanation:
We leave a soda in the car overnight and the temperature dips to 25 °F. To see if it will freeze we have to convert the °F to °C.
T(°C) = ( T(°F) - 32 ) *5/9
T(°C) = (25 - 32) *5/9
T(°C) = -3.9 °C
Since -3.9 °C is a temperature greater than the freezing point (-4.5 °C) the soda won't freeze.
Answer: The soda won't freeze.
Answer:
It means these compounds are only made up of two elements.
Explanation:
Binary compounds:
The compounds which are made up of the atoms of only two elements are called binary compounds.
For example:
The following compounds are binary:
HCl
H₂O
NH₃
HCl is binary because it is composed of only hydrogen and chlorine. Ammonia is also binary compound because it is made up of only two elements nitrogen and hydrogen.
water is also binary because it is also made up of only two elements hydrogen and oxygen.
While all polyatomic compounds are not binary. for example,
H₂SO₄
It is made up of hydrogen, sulfur and oxygen. There are three elements are present in this compound. So, it is not binary compound.
