What's a tungsten atom
Is a chemical element with the symbol W and with an atomic number 74.
1.328 × 10⁻¹⁰ Ag atoms
Explanation:
To find the number of moles we use the Avogadro's number to formulate the following reasoning:
if in 1 mole of Ag there are 6.022 × 10²³ Ag atoms
then in X moles of Ag there are 8 × 10¹³ Ag atoms
X = (1 × 8 × 10¹³) / ( 6.022 × 10²³) = 1.328 × 10⁻¹⁰ Ag atoms

Answer is: Rutherford demonstrate that <span>J.J Thompson's Plum Pudding model was not accurate.
</span><span>Rutherford theorized
that atoms have their charge concentrated in a very small nucleus.
</span>This was famous
Rutherford's Gold Foil Experiment: he bombarded thin foil of gold
with positive alpha particles (helium atom particles, consist of two protons and two neutrons).
Rutherford observed the
deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil.
That is different from Plum Pudding model<span>, because it shows that most of the atom is empty space.</span><span>

Since the onion (Allium cepa) is a diploid organism having a haploid genome size of 15.9 Gb, it has 4.9x as much DNA as does a human genome (3.2 Gb). Other species in the genus Allium vary hugely in DNA content without changing their ploidy.
Answer is: mass of methanol is 528.32 grams.
N(CH₃OH) = 9.93·10²⁴; number of methanol molecules.
n(CH₃OH) = N(CH₃OH) ÷ Na (Avogadro constant).
n(CH₃OH) = 9.93·10²⁴ ÷ 6.022·10²³ 1/mol.
n(CH₃OH) = 16.49 mol; amount of substance.
m(CH₃OH) = n(CH₃OH) · M(CH₃OH).
m(CH₃OH) = 16.49 mol · 32.04 g/mol.
m(CH₃OH) = 528.32 g.
