Answer:

\boxed {\boxed {\sf v \approx 1.88 \ mL}}

Explanation:

The density formula is:

d=\frac{m}{v}

If we rearrange the formula for volume, the result is:

v=\frac{m}{d}

The mass of the object is 32 grams. The density is 17 grams per milliliter.

m= 32 \ g\\d= 17 \ g/mL

Substitute the values into the formula.

v=\frac{32 \ g}{17 \ g/mL}

Divide. Note that the grams, or g, will cancel each other out.

v=\frac{32 }{17 \ mL}

v=1.88235294 \ mL

Let's round to the nearest hundredth to make the answer more concise.

The 2 in the thousandth place tells us to leave the hundredth place as is.

v \approx 1.88 \ mL

The volume of the object is about <u>1.88 milliliters. </u>

Explanation:

here,

Mass (m)= 32 g =0.32 kg

Density(d)= 17 g/ml

volume (v)=?

we know that,

d=m/v

17=0.32/v

v= 0.32/17

v=0.018<u> </u>

Given a fixed amount of gas held at constant pressure, calculate the volume it would occupy if a 2.00 L sample were cooled from
aliina [53]

Answer:

1.82 L

Explanation:

We are given the following information;

  • Initial volume as 2.0 L
  • Initial temperature as 60.0°C
  • New volume as 30.0 °C

We are required to determine the new volume;

From Charles's law;

\frac{V_1}{T_1}=\frac{V_2}{T_2}

Where, V_1 and V_2 are initial and new volume respectively, while T_1 and T_2 are initial and new temperatures respectively;

T_1= 333 K

T_2=303K

V_1 =2.0L

Rearranging the formula;

V_2=\frac{V_1T_2}{T_1}

    = \frac{(2.0L)(303K)}{333K} \\=1.820 L

Therefore, the new volume that would be occupied by the gas is 1.82 L

Estimate ΔH for the reaction using bond dissociation energies from Table 7.1. Give your answer in kcal. C6H12O6 has five C−C bon
Nat2105 [25]

The equation for the photosynthesis reaction in which carbon dioxide and water react to form glucose is . The hear reaction is the difference between the bond dissociation energies in the products and the bond dissociation energies of the reactants

 

The reactant molecules have 12 C = O, 12 H - O bonds while the product molecules have 5 C - C, 7 C – O, 5 H – O, and 6 O = O bonds. The average bond dissociation energies for the bonds involved in the reaction are 191 for C = O, 112 for H – O, 83 C –C, 99 C – H, 86 C – O, 119 O = O.

 

Substitute the average bond dissociation energies in the equation for and calculate as follows

= [12 (C=O) + 12 (H-O)] – [5(C-C) + 7(C-H) + 7 (C-O) + 5(H-O) + 6(O=O)]

= [12x191 kcal/mol + 12x112 kcal//mol] – [5x83 kcal/mol + 7x99 kcal/mol + 7x86 kcal/mol + 5x112 kcal/mol + 6x119 kcal/mol]

= 3636 kcal/mol – 2984 kcal/mol = 652 kcal/mol x 4.184 Kj/1kcal = 2.73x10^3 kJ/mol

 

So, enthalpy change for the reaction is 652 kcal/mol or 2.73x10^3 kJ/mol
