Molar mass of NaOH is 40g/mole

Since you are given 0.10 moles of NaOH you will use this number to convert from moles to grams by using the molar mass. Here’s how it is done.

You must use a conversion factor and you already found one! 40g of NaOH per mole. So

0.10 mole NaOH = 40g NaOH = 4 g NaOH
—————-
1 mole NaOH


(The top is multiplied straight across and the bottom is also multiplied straight across, then the top and bottom is divided in the end to get 4g of NaOH)

Answer:

Option E, Half life = 2.96\times 10^3\ s

Explanation:

For a first order reaction, rate constant and half-life is related as:

            t_{1/2}=\frac{0.693}{k}

Where,

t_{1/2} = Half life

k = Rate constant

Rate constant given = 2.34\times 10^{-4}\ s^{-1}

t_{1/2}=\frac{0.693}{k}

=\frac{0.693}{2.34 \times 10^{-4}}=2.96\times 10^3\ s

So, the correct option is option E.

What is the mass of 1.25 L of ammonia gas at STP
Alex73 [517]

Answer:

mass 1.25 Liters NH₃(gas) = 0.949 grams (3 sig-figs)

Explanation:

At STP (Standard Temperature-Pressure conditions => 0°C(=273K) and 1atm pressure,  1 mole <u>any</u> gas will occupy 22.4 Liters.

So, given 1.25 Liters ammonia gas at STP, convert to moles then multiply by formula wt. (17g/mole gives mass of NH₃.

moles NH₃(gas) = 1.25L NH₃(gas)/22.4L NH₄(gas)· NH₃(gas)mole⁻¹ = 0.0558 mole NH₃(gas).  

Converting to grams NH₃(gas) = 0.0558 mole NH₃(gas) x 17 g·mol⁻¹ = 0.949 grams NH₃(gas).
