Given the concentration (C) in mass per volume, the volume (V) of the solution is obtained by dividing the mass (m) by this concentration (C). So, from the given,
                         V = C / m   = (15 g) / (75 g / 1000 mL)
The numerical value of V is equal to 200 mL.

I would start by converting g/mL to g/L
75.00g/1000.0mL = 75.00g/L
Stoichiometrically, flip 75 onto the bottom so that grams cancel out and we are left with the number of L required. 
(L/75.00g)(15g) -> this is essentially dividing 15g by 75g, which cancels the unit g, leaving us with 0.2L. If the question requires an answer in mL, just multiple the number of L by 1000. 
The patient requires 200mL of glucose solution to receive his 15g of glucose.

What can you infer about the volume of a gas as absolute zero is approached?
schepotkina [342]

Answer:

The volume of a gas approaches zero as the temperature approaches absolute zero.

Step-by-step explanation:

You may have done a <em>Charles' Law experiment</em> in the lab, in which you measured the volumes of a gas at various temperatures.

You plotted them on a graph, and perhaps you were asked to extrapolate the graph to lower temperatures.

Your graph probably looked something like the one below.

There is clearly an x-intercept at some low temperature.

Inference: The volume of a gas approaches zero as the temperature approaches absolute zero.

Anybody wana do this? Lol much appreciated.
Alex73 [517]
No units are provided in the data table, though one would usually assume that 0.244 is molarity of NaOH, and buret data of 14.7 is probably the final volume of NaOH in mL. No identification is given for the 38, but maybe this is the initial buret volume in mL.

If the buret was rinsed with water, it should have been left to dry for some time, or else the added water may slightly dilute the NaOH solution placed in it.

How many grams of sodium hyrdioxde are in 251.0ml f 0.600m
Furkat [3]

Answer:

There are 6.024 grams of sodium hydroxide in the solution.

Explanation:

Molarity=\frac{Moles}{Volume (L)}

Moles (n)=Molarity(M)\times Volume (L)

Moles of sodium hydroxide = n

Volume of sodium hydroxide solution = 251.0 mL = 0.251 L

Molarity of the sodium hydroxide = 0.600 M

n=0.600 M\times 0.251 L=0.1506 mol

Mass of 0.1506 moles of NaOH :

40 g/mol\times 0.1506 mol = 6.024 g

There are 6.024 grams of sodium hydroxide in the solution.
