If an object is travelling 25.0 meters/second, how far will it travel in 45 minutes?

Misha Larkins [42]

Speed=25m/s
Time=45min=(45×60)s=2700s

$\\ \rm\longmapsto Distance=Speed(Time)$

$\\ \rm\longmapsto Distance=25(2700)$

$\\ \rm\longmapsto Distance=67500m$

To a 25.00 mL volumetric flask, a lab technician adds a 0.250 g sample of a weak monoprotic acid, HA , and dilutes to the mark w

Basile [38]

Answer: The number of moles of the weak acid in the solution is 0.00396

Explanation:

To calculate the number of moles for given molarity, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}$

a) ${\text{Moles of}KOH=0.0846M\times 0.04683L=0.00396mol$

The balanced chemical reaction is:

$HA+KOH\rightarrow KA+H_2O$

1 mole of base uses = 1 mole of $HA$

0.00396 moles of base use = $\frac{1}{1}\times 0.00396=0.00396$ moles of $HA$

Thus the number of moles of the weak acid in the solution is 0.00396
