Explanation:
if there is no number behind the element, it counts as one, but if there is, you do 1 times x(whatever the exponent is) and thats how many that one element counts for with atoms. then you just add them all up
C. fluid
is the correct answer
The correct answer to this question is the unique atomic number which would be B
I think this question is a true statement :)
The molecular formula of sucrose is - C₁₂H₂₂O₁₁
molecular mass of sucrose - 342 g/mol
molarity of sucrose solution is 0.758 M
In 1 L solution the number of sucrose moles are - 0.758 mol
Therefore in 1.55 L solution, sucrose moles are - 0.758 mol/L x 1.55 L
= 1.17 mol
The mass of 1.17 mol of sucrose is - 1.17 mol x 342 g/mol = 4.00 x 10² g
