How many moles are present in 150g of ammonium hydrogen phosphite

Chemistry

The moles  that  are  present  in 150 g  of ammonium  hydrogen phosphite  is  1.136 moles


       <u><em>calculation</em></u>

<em>The formula  of ammonium hydrogen  phosphite = (NH4)2HPO4</em>

moles = mass/molar mass

mass= 150 g

molar mass of (NH4)2HPO4  =  [ ( 14+ 1x4)2)  +1 + 31  + ( 4 x16)] =132 g/mol

 moles is therefore = 150  g/ 132 g/mol  =1.136  moles

Sophie [7]

Answer:

80.1 grams

Explanation:

Find the molar mass of CH3OH first by using the periodic table values.

12.011 g/mol C + (1.008*3 g/mol H) + 15.999g/mol O + 1.008 g/mol H

=32.042 so that is the molar mass

Now that you have 2.50 moles of CH3OH, you can calculate the mass in g

2.50molCH3OH * (32.042g CH3OH / 1 mol CH3OH) = 80.105

32.042g / 1 mol is the same as 32.042 g/mol

Since there are 3 sig figs in the problem (2.50 has 3 sig figs), you round to 80.1 g CH3OH

What is the density of object A? Does it sink<br> or float in water?
Oksana_A [137]

Answer:

~1.5 g/cm3 and it does NOT float in water.

Explanation:

If you look at the graph, Object A weighs ~6 grams and is ~4 cm3 in volume

Density = Mass/Volume

So 6 grams/4 cm3 = 1.5 g/cm3

Water has a density of 1 g/cm3 and because Object A density is higher than that of water, it sinks.
