Xenon is an element similar to Neon. Its density can be found on the Reference Table. Convert Xenon’s density to scientific nota

Nady [450]

The Scientific Notation of Xenon’s density : 1.31293 × 10²

<h3>Further explanation</h3>

Scientific Notation consists of 2 parts

1. the first part: the first digit followed by the decimal point

2. The second part: the power of 10 which shows the number of digits after the decimal point

Xenon's density = 131.293

First digit = 1, then we give the decimal point and the next digit

The power of 10 is determined from the number of decimal points moved from the original decimal point

Because we move the decimal point two digits to the left, the power of 10 has the number 2 (10²)

So that the Scientific Notation form becomes:

1.31293 × 10²

If a muriatic acid solution has a pH of 2.50, what is the hydronium ion concentration (hydronium ion concentration is also the m

Irina18 [472]

Answer:

[H₃O⁺] = 0.032 M

Explanation:

The acidity of a solution is measured by its pH, which is the logarithm of the inverse of the molar concentration of hydronium (H₃O⁺) ions:

pH = log 1 / [H₃O⁺] = - log [H₃O⁺]

When you know the pH value you can find hydronium concentration using the antilogaritm function:

$pH=-log[H_3O^{+}]\\ \\ {[H_3O^+]}=10^{-pH}\\ \\ {[H_3O^+]}=10^{-2.50}\\ \\ {[H_3O^+]}=0.0032$

The unit of molar concentration is M.

To prove your answer you can take the logarithm of 0.0316:

log (0.0032) ≈ 2.500
