Specific heat capacity (c) of a material is related to the Energy Absorbed (Q), mass of the material (m) and the change in temperature (T) by the following equation:

c= \frac{Q}{mT}

Substituting the values of Q, m and T in the above equation, we get:

c= \frac{48.75}{15.1*25}=0.129

So the specific heat capacity of the metal with given conditions will be 0.129 J/g.K

How many atoms of S are in 98.0 grams of hydrosulfuric acid?
noname [10]
<h2>Answer:6.022\times 10^{23}</h2>

Explanation:

The formula for sulphuric acid is H_{2}SO_{4}.

Molecular mass of sulphuric acid is 2(2)+32+16(4)=98g

given weight=98g

Number of moles of sulphuric acid given is \frac{\text{given weight}}{molar mass}=\frac{98}{98}=1

The formula indicates that one mole of H_{2}SO_{4} contains 2 moles of H atoms,1 mole of S atoms,4 moles of O atoms.

So,the compound contains 1 mole of sulphur atoms.

1 mole of sulphur has 6.022\times 10^{23} atoms

The wavelength of the characteristic, bright yellow-orange flame test color of sodium is 590 nm. Calculate the average energy (Δ
Assoli18 [71]
<span>The energy associated with the 590nm atomic emission line is 3.369 x 10^49 Joules. This can be determined by multiplying Plank’s constant (6.626 x 10^34 Js) by the speed of light (3x 10^8 m/s), and then dividing the result by the wavelength (590 x 10^-9 m).</span>

Calculate the mass of KI in grams required to prepare 5.00 X10^2 mL of a 2.80 M solution
grandymaker [24]
Volume in liters:

5.00x10² mL / 1000 => 0.5 L

Molar mass KI => 166.0028 g/mol

Mass KI = volume x molar mass x molarity

Mass KI = 0.5 x 166.0028 x 2.80

= 232.40392 g of KI

hope this helps!
