68/100 (fraction) which can simplify to 17/25 and 6.8x10-1 (scientific notation)
The answer will depend on .068 WHAT!
When carbonic acid reacts with 2 equivalents of OH-, it forms bicarbonate and water.
There are 1.20 equivalents in 0.60 mole of Mg2+, since Mg2+ has a charge of 2+.
{
There are 2.75 equivalents of Mg^2+ present in a solution that contains 2.75 mol of Mg^2+. This is because the number of equivalents is equal to the number of moles for ions with a +2 charge.

When carbonic acid reacts with 2 equivalents of hydroxide ions, it forms water and carbonate ions.
068 = 68... So 68/1 - Sixty Eight over One would be the answer...
068 is an integer and already rounded to more than 1 dp.
3 equivalents fractions for 0.20 = 2/10, 1/5, 4/20
