9*11 = 9*(10 + 1) = 9*10 + 9*1 = 9*10 + 9.

To find the number of moles in (1.63 \times 10^{24}) atoms, you can use Avogadro's number, which is approximately (6.022 \times 10^{23}) atoms per mole. Divide the number of atoms by Avogadro's number: [ \text{moles} = \frac{1.63 \times 10^{24}}{6.022 \times 10^{23}} \approx 2.71 \text{ moles}. ] Thus, there are approximately 2.71 moles in (1.63 \times 10^{24}) atoms.
To find the hydronium ion concentration in an aqueous solution, you can use the relationship between the concentrations of hydronium ions ([H_3O^+]) and hydroxide ions ([OH^-]) given by the ion product of water at 25°C, which is (K_w = [H_3O^+][OH^-] = 1 \times 10^{-14}). Given that ([OH^-] = 1 \times 10^{-11} , M), you can rearrange the equation to find ([H_3O^+]): [ [H_3O^+] = \frac{K_w}{[OH^-]} = \frac{1 \times 10^{-14}}{1 \times 10^{-11}} = 1 \times 10^{-3} , M. ] Thus, the hydronium ion concentration is (1 \times 10^{-3} , M).
if you ignore the initial 5times for now there is actually a button for this kind of calculation on your calculator(scientific- but still cheap mine was £10) it is shown as x! in this case 10! is 3628800 and remembering the initial 5times= 18144000 this kind of calculations are used for figuring possible combinations of letters and numbers.
It is 2 times.It is 2 times.It is 2 times.It is 2 times.
10 multiplied by 147 is 1,470.
100 is 10 times 10. 100 periods: ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... .....
401/5 = (10 times 40.1) / (10 times 5) The (10 times) factors in numerator and denominator cancel out so that 401/5 = 40.1/.5
1 remainder 6
