Studdy Solution

STEP 1

Assumptions1. The volume of CH3OH\mathrm{CH}_{3} \mathrm{OH} is 150.0 m150.0 \mathrm{~m} . The molarity of CH3OH\mathrm{CH}_{3} \mathrm{OH} is 0.210M0.210 \mathrm{M}

STEP 2

First, we need to convert the volume from milliliters to liters, as molarity is defined as moles per liter.
Volumeinliters=Volumeinmilliliters/1000Volume\, in\, liters = Volume\, in\, milliliters /1000

STEP 3

Now, plug in the given value for the volume in milliliters to calculate the volume in liters.
Volumeinliters=150.0 m/1000Volume\, in\, liters =150.0 \mathrm{~m} /1000

STEP 4

Calculate the volume in liters.
Volumeinliters=150.0 m/1000=0.150 Volume\, in\, liters =150.0 \mathrm{~m} /1000 =0.150 \mathrm{~}

STEP 5

Now that we have the volume in liters, we can find the quantity in moles. This can be done by multiplying the volume in liters by the molarity.
Quantityinmoles=VolumeinliterstimesMolarityQuantity\, in\, moles = Volume\, in\, liters \\times Molarity

STEP 6

Plug in the values for the volume in liters and the molarity to calculate the quantity in moles.
Quantityinmoles=0.150 times0.210MQuantity\, in\, moles =0.150 \mathrm{~} \\times0.210 \mathrm{M}

STEP 7

Calculate the quantity in moles.
Quantityinmoles=0.150 times0.210M=0.0315 molesQuantity\, in\, moles =0.150 \mathrm{~} \\times0.210 \mathrm{M} =0.0315 \mathrm{~moles}The quantity in moles of CH3OH\mathrm{CH}_{3} \mathrm{OH} in 150.0 m150.0 \mathrm{~m} of 0.210MCH3OH0.210 \mathrm{M} \mathrm{CH}_{3} \mathrm{OH} is 0.0315 moles0.0315 \mathrm{~moles}.
