I think a scientific STATEMENT could be answer C
Answer:
m = 29.6 grams
Explanation:
Given that,
Number of moles = 0.540
The molar mass of manganese = 54.93 g/mol
We know that,
Number of moles = given mass/molar mass
So, the required mass of the Manganese is equal to 29.6 grams.
Answer: The molarity of is 0.07 M
Explanation:
According to the neutralization law,
where,
= basicity = 1
= molarity of solution = ?
= volume of solution = 25.0 ml
= acidity of = 1
= molarity of solution = 0.1000 M
= volume of solution = 17.5 ml
Putting in the values we get:
Therefore, molarity of is 0.07 M
Chemical formula that shows the totalnumber and kinds of atoms in a molecule,but not their structural arrangement. Forexample, the molecular formula of aspirinis C9H8O4. Compare empirical formulastructural formula .
contains 4.92% hydrogen and 26.18% oxygen. The molar mass of the compound is 244.25 g/mol
