One minus two equals negative one and three minus five equals negative two
Answer:
4.86 × 10^-7m
Explanation:
Wavelength = C/f
C (Speed) of light = 3 × 10^8
f = 6.17 × 10^14
Wavelength = (3 × 10^8)/ (6.17 × 10^14)
= 4.86 × 10^-7m
Gas.
A gas has no fixed shape as it takes shape of container.
It has no fixed volume as it depends on the container.
Answer:
In 2.00 moles of carbon disulfide, we have 4.00 moles of sulfur atoms
Explanation:
Step 1: Data given
Number of moles of CS2 = 2.00 moles
Step 2: Calculate moles of sulfur atoms
In 1 mol CS2 we have 2 moles sulfur
This means per 1 mol CS2 we'll have 2 sulfur atoms.
For 2.00 moles of CS2 we have 2*2.00 = 4.00 moles of sulfur
In 2.00 moles of carbon disulfide, we have 4.00 moles of sulfur atoms
