Analyzing molar mass calculation

I’m considering the molar mass of water, which might be M(H2O) = 18.2 g/mol. If the task asks for N given m = 2.70 g and M = 18.2 g/mol, I could calculate N using Avogadro’s number. So, N = (2.70/18.2) * 6.02e23, which gives approximately 8.93e22. But I’m wondering if the M value is correct since it might be handwritten as "18,?" instead. It looks like I need to zoom in on an uploaded image to verify.Evaluating molecular mass calculation

I'm looking at the expected calculation using the formula \(N = \frac{m}{M} N_A\). I've got the mass of water as \(2.70\) g and the molar mass as \(18.2\) g/mol, but I wonder if I should just stick with \(18\) g/mol for clarity. There’s a chance that the scribble reflects a units mix-up. I should aim for a clean response using the given values. Let's extract the information from the image as needed.Calculating molecular mass and moles

I'm trying to decipher some chemical data. It looks like the molecular mass of water is indicated as "M(H₂O)=18,2 г/моль." Initially, I see there might be an error with the decimal, as it could also be 18.2. I need to respect the given data, although it might be inaccurate.

There's also a mass given as m(H₂O)=2,70, which likely means 2.70 grams. My calculations lead me to find the number of molecules, which turns out to be approximately \(8.93 \times 10^{22}\).Clarifying molecular mass

I'm weighing some molecular data regarding water. If the molar mass \(M\) is 18, the resulting number of molecules is \(9.03 \times 10^{22}\). The mass given as 2,70 and \(M(H_2O)=18,2 \mathrm{г/моль}\) could stem from a pedagogical choice, yet I need to use it as presented. However, it's confusing since students expect accuracy in chemistry, and 18 g/mol could be a more typical value. I notice potential discrepancies with the “г” symbol in the image, which adds to my uncertainty.Calculating mole quantity

I’m trying to follow the visible data. Using \(N_A=6.02\times10^{23}\) and a mass of 2.70g, I calculate the number of moles, which gives me \(N=8.93\times10^{22}\).

To be clear, the formula I’m using is: \[ N(\mathrm{H_2O})=\frac{m}{M}N_A \] If I were to consider 18 g/mol as the standard molar mass, the answer varies, but the user wants a concise response. The image indicates the mass, and I should include the necessary formula while possibly responding in Russian.Determining the next step

I could suggest "Реши следующий пример на количество вещества," but that might be unnecessary. The developer mentions adding a single line for a meaningful next move, which I’m considering.

I think I'll append [[NEXT]] Реши аналогичную задачу для CO₂. That seems natural and prompts the user for a related task that hasn’t been solved yet. However, I need to remember that the user may just want the answer, and the marker is a system-generated part they expect.
