marishachu [46]

Answer:

3.00 × 10¹¹ g

Explanation:

According to the United States Department of Agriculture (USDA), Texas had 4,015,000 beef cows in 2013. One beef cow produces 205 grams of methane per day. The methane produced by the beef cows in Texas per day is:

$4,015,000Cow \times \frac{205gCH_4}{cow \times day} = \frac{8.23 \times 10^{8}gCH_4}{day}$

Each year has 365 days. The methane produced by the beef cows in Texas per year is:

$\frac{8.23 \times 10^{8}gCH_4}{day} \times \frac{365day}{1y} = 3.00 \times 10^{11}gCH_4$

How many moles of nitrate are dissolved in water if 6.15 mole strontium nitrate dissolve?

pashok25 [27]

The number of moles of nitrate dissolved in water if 6.15 mole of strontium nitrate is : 12.3 moles

<u>Given data :</u>

Moles of strontium nitrate = 6.15 moles

<h3>Ionization of Strontium Nitrate </h3>

When strontium nitrate ( $Sr(NO_{3} )_{2}$ ) is placed in water it will dissociates into its ions because strontium nitrate is an ionic compound.

Next step : Represent the ionization of strontium nitrate

$Sr ( NO_{3} )_{2} (aq) --- > Sr^{2+} (aq) + 2NO_{3} ^{-} (aq)$

From the Stoichiometry of the chemical reaction

I mole of strontium nitrate = 2 moles of Nitrate ions

6.15 mole of strontium nitrate = 2 * 6.15

= 12.3 moles of Nitrate

Hence we can conclude that The number of moles of nitrate dissolved in water if 6.15 mole of strontium nitrate is : 12.3 moles.
