Answer:
The cell membrane is protective layer surrounding a cell.
H %= 100- (52.14 + 34. 73) equals 13.13 %
Assuming 100 g of this compound
Mass H= 13.13 g
Moles H= 13.13 g ÷ 1.008g/ moles= 13
Mass C= 52.14 g
Moles C= 52.14 g ÷ 12.011 g/ moles= 4
The empirical formula is C4H1302
Answer:
Mercury is an liquid metal
Explanation:
Mercury is a chemical element with the symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum.
Symbol: Hg
Explanation: The atomic mass of iron (Fe) is 55.85 amu. The atomic mass of radium (Ra) is 226 amu. One mole of atoms of any element contains 6.022 X 1023 atoms, regardless of the type of element. The mass of one mole of an element depends on what that element is, and is equal to the atom mass of that element in grams.
