Calculate the concentration, in units of dm-3, of sulfuric acid, H2SO4, which has a solubility of 2 mol dm-3. [Relative atomic m
olga55 [171]

Answer:

196 gdm-3

Explanation:

There are two major units of concentration, moldm-3 and gdm-3. The first unit refers to molar concentration while the second unit refers to mass concentration. Both units are useful in chemistry when describing the concentration of solutions as deemed expedient in each particular case.

Here we are required to compute the mass concentration from the molar concentration. We must recall that; mass concentration= molar concentration × molar mass

Let us first obtain the molar mass of H2SO4 from the relative atomic masses given=

2(1) + 32 + 4(16) = 98 gmol-1

Molar concentration of H2SO4 = 2 moldm-3

Mass concentration= 2 moldm-3 × 98 gmol-1

Mass concentration = 196 gdm-3

What is it with the name Sara these days!? XD
Komok [63]

66 mph

Explanation:

Average speed is the rate of change of distance with time:

       Average speed = \frac{Distance }{time}

Given parameters:

Starting point = 88mile marker

End of journey = 121mile marker

time = 30minutes = 0.5hr(60min = 1hr)

Solution:

The distance covered in this journey:

  Distance = End of journey - starting point = 121 mile - 88 mile = 33mile

 Average speed = \frac{33miles}{0.5hr}

                            = 66mph

The average speed of Sara's mum is 66mph
