Answer:
9.09cm3
Explanation:
The following data were obtained from the question:
Mass of dimethyl sulfoxide = 10g
Density of dimethyl sulfoxide = 1.10gcm−3
Volume of dimethyl sulfoxide =?
The density of a substance is simply the mass substance per unit volume of the substance. It is represented mathematically as:
Density = Mass/volume.
With the above formula, we can obtain the volume of dimethyl sulfoxide as follow:
Density = Mass/volume
1.10gcm−3 = 10g/ volume
Cross multiply to express in linear form
1.10gcm−3 x Volume = 10g
Divide both side by 1.10gcm−3
Volume = 10g / 1.10gcm−3
Volume = 9.09cm3
Therefore, the volume of dimethyl sulfoxide the student should pour out is 9.09cm3
