Answer:
5*10^25 atoms of carbon
Explanation:
<u>Check from the periodic table:</u>
M(carbon) = 12.01 g/mol
<u>Convert kg into g:</u>
1 kg = 1000 g
<u>Calculate the number of moles of carbon:</u>
n(carbon) = (1000 g) ÷ (12.01 g/mol) = 83.26 mol
<u>Convert moles into number of particles:</u>
#(carbon) = n × NA = 83.26 mol × 6*10^23
= 5*10^25 particles
<em>N</em><em>o</em><em>t</em><em>e</em><em>:</em><em> </em><em>NA represents the Avogadro's Number, which has the value 6.02*10^23 particles/mol</em><em>.</em>

Explanation:
P.E=0.0675 J
Explanation:
Elastic potential Energy=Force × distance of displacement
The formula to apply is;
P.E=1/2 ks²
where k is the spring constant given as; 1.5 *10^-2 N/m and s is the displacement
In this case,
s=3
P.E= 1/2 * 1.5 × 10^-2 ×3²
P.E=1.5×10^-2*4.5
P.E=0.0675 J
