What you would want to do here is dividing mass by density. In fact, density is referred to as a ratio of mass to volume. There is no need for any unit conversion as they are already comparable. So the result should be 105g / 11.3g/ml =9.3ml.
English is not my first language, so sorry for language issues of any kind.
Answer:
Option d is correct option = Frequency of light is 6.56×10⁻² Hz
Explanation:
Given data:
Frequency of light = ?
wavelength of light = 4.57×10⁹m
Solution:
Formula:
Speed of light = wavelength × frequency
c = λ × f
f = c/λ
This formula shows that both are inversely related to each other.
The speed of light is 3×10⁸ m/s
Frequency is taken in Hz.
It is the number of oscillations, wave of light make in one second.
Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.
Now we will put the values in formula.
f = 3×10⁸ m/s / 4.57×10⁹m
f = 0.656×10⁻¹s⁻¹
s⁻¹ = Hz
f = 0.656×10⁻¹ Hz or 6.56×10⁻² Hz
Answer:
n = 2 moles (1 sig-fig)
Explanation:
Using the Ideal Gas Law equation (PV = nRT), solve for n (= moles) and substitute data for ...
pressure = P(atm) = 100atm
volume =V(liters) = 50L
gas constant = R = 0.08206L·atm/mol·K
temperature = T(Kelvin) = °C + 273 = (35 + 273)K = 308K
PV = nRT => n = PV/RT = (100atm)(50L)/(0.08206L·atm/mol·K)(308K)
∴ n(moles) = 1.978moles ≅ 2 moles gas (1 sig-fig) per volume data (= 50L) that has only 1 sig-fig. (Rule => for multiplication & division computations round final answer to the measured data having the least number of sig-figs).
