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

Answer:
Explanation:
percentage abundance of third isotope = 100 - ( 78.900 + 10.009)
= 11.091 %
Atomic mass
24.1687 x .789 + 25.4830 x .10009 + 24.305 x .11091
19.069 + 2.5506 + 2.69566
= 24.3153 amu
Different isotopes of the same element emit light at slightly different wavelengths, the minimum number of slits is mathematically given as
N=1820slits
<h3>What minimum number of slits is required to resolve these two wavelengths in second-order?</h3>
Generally, the equation for the wave is mathematically given as
Where the chromatic resolving power (R) is defined by
R = nN,
Therefore
and
In conclusion, the minimum number of slits is required to resolve these two wavelengths in second-order
Therefore
N=1820slits
