<span>The starting material must be CO2 that can be fixed or turned into other molecules. </span>
We are given with the titration with <span> 0.100 M NaOH obtained at 15.00 mL. The moles equivalent of HCl here is equal to 0.1*15x10^-3 or 0.0015 moles. This is equivalent to 0.055 grams HCl. the percent purity then is equal to 0.055/0.5725 or 9.55%.</span>
Answer:
Modern recorders are most commonly pitched at A=440 Hz, but among serious amateurs and professionals, other pitch standards are often found. For the performance of baroque music, A=415 Hz is the de facto standard, while pre-Baroque music is often performed at A=440 Hz or A=466 Hz.
Explanation:
Answer:
Density,
Explanation:
Given that,
Mass of the sample, m = 55.6 grams
The sample is submerged in water and 27.3 mL of water is displaced.
We need to find the density of a sample of an small asteroid. It is equal to the mass of the object per unit volume.
1 mL = 1 cm³
So,
So, the density of the sample is .
