Repeat trials multiple times
In an acid and base neutralization reaction, the products are salt and water.
The option in “the mass of 1me of carbon equals the mass of 1 mole of boron atoms” is false since
Mass=molesx molar mass
And the molar masses of these two elements are different so their masses aren’t equal
First find the RFM (Relative Formula Mass) using a periodic table
the RFM of Ca(OH)2 is = 74
then use the equation Moles = Mass / RFM
Moles = 7.4 / 74 = 0.1mol
