Answer:
75 ml of 0.1M base neutralizes 25 ml of 0.1M acid, which means the acid has 0.3 moles/L of H ion
but that means each molecule of the acid has 3 times as many H ions aH ions in a molecule of NaOH
which means the formula for the acid must be H3A and
the value of x in
HxA is 3
Explanation:
75ml of a solutipn of 0.1moL l-1 NaOH neutralises 25ml of a solution of an acid. The formula of the acid is HxA and the concentration of the acid is 0.1mol l-1. What is the value of x?
the concentration of both the and the base are the same at 0.1M
the base...NaOH has 0.1 moles/L of OH ion
75 ml of 0.1M base neutralizes 25 ml of 0.1M acid, which means the acid has 0.3 moles/L of H ion
but that means each molecule of the acid has 3 times as many H ions aH ions in a molecule of NaOH
which means the formula for the acid must be H3A and the value of x in
HxA is 3
<span>1 fm = 1.0 × 10-15 meters
</span>so
0.610<span> fm x (1.0x10^-15 m / 1 fm)
= 6.1x10^-16 m</span>
so the formula is
λ = h / mu
so,
as we know mass value so by putting
<span>m = (6.626*10^-34)/(6.1*10^-16*199)
=</span>(6.626*10^-34)/(1213.96*<span>10^-16)
</span><span> = 5.45 x 10^ -21
hope thats an answer for you</span>
