Assuming the reaction is first order in sucrose, determine the mass of sucrose that is hydrolyzed when 2.75 L of a 0.130 M sucro
Advocard [28]

Answer:125.84g

Explanation:Sucrose is dissacharides an organic compound in the class of carbonhydrate with the chemical formula C11H22O11.molar concentration is given by number of moles/Volume,this implies that moles=molar concentration ×Volume=0.130M×2.75L=0.3575moles.

Furthermore,number of moles=Mass of Sucrose/molecular Mass of Sucrose.

From it's formular C11H22O11, molecular Mass is the addition of the mass number which is 12 for C,2 for H and 16 for oxygen,O.so molecular Mass of Sucrose is (12×11)+(2×22)+(16×11)=352.

So mass =moles ×molecular mass=0.3575moles×352g/moles=125.84g

How many carbon atoms are there in a 1.5-carat diamond? diamonds are a form of pure carbon. ( 1 carat=0.20 grams)?
11111nata11111 [884]
1 carot = 0.2 grams
1.5 carot = 0.3 grams.

1 mol of Carbon = 12 grams
x mol = 0.3 grams

0.3 * 1 = 12 x
x = 0.3/12
x = 0.025 mol

1 mol of Carbon is 6.02 * 10^23 atoms
0.025 mol of carbon is x

1/0.025 = 6.02*10^23 * /x
x = 0.025 * 6.02 * 10^23
x = 1.5 * 10^22 atoms of carbon.

Einstein’s Theory of Relativity was built on the research and ideas of other scientists. The Theory of Relativity proposes that the speed of light is aconstant. The statement that explains why this is considered to be a scientific theory is that the majority of the scientific community voted on this theory over other possible explanations.
